There was a couple of tourists passed by a farm where they had a three legged pig. Courteously they knocked on the farmers door to inquire about the pig as to why it only had three legs.
The farmer told him that it was a very special pig, "At one time when our daughter Judy was swimming in the pond and almost drowned that very pig, got all excited, came running up to the house, got our attention, and we went down to the pond and rescued Judy."
"Then another time, when the barn started on fire that same pig came running and got our attention, and we were able to save the farm."
"Yep that's one special pig and when you got one that special, you don't want to eat it all at once!"
